- The objects of this invention are': First, to provide a device for breaking up and difiusing the mixture of airand fuel used in an internal combustion engine.

Second, to provide such a device that assures a stable mixture.

Third, to provide such from such mixture the entrained fuel and delivers to the engine a dry mixture. 7

Fourth, to provide such a device that assures 1 complete lubrication: by, eliminating fuel in the fluidstate from the mixture fed to the engine.

Fifth, to provide such a device that can be;

easily and quickly installed in any automobile engine or ther internal combustion engine.

Sixth, to provide sucha device that'may be 1 Further. objects" and advantages of construction and operation will appear from the description to follow. *Apreferred embodimentof my invention is illustrated in the accompanying drawing, in which:

Fig. 5.is-a detail sectional view of the dished portion of one of the axial vanes, taken on line 55 of Fig. 3.

The parts will be identified by their numerals of reference which are the same in all the views. I show my invention in connection withia carburetor l of conventional form, shown in dotted lines in Fig. 1, and an intake manifold 2 of an internal combustion engine having an up-draft portion 3 secured by flange 4 to flange '5 on said carburetor by means of bolts 6. Gaskets '7 are provided between said flanges.

My invention consists of a plurality of crossed metal strip members 8 having their ends spiral- 1y twisted a half turn or more to form blades 9. The members 8 are arranged criss cross so that a member having a plurality of spirally. twisted blades 9 is disposed across the up-draft a device that removes portion 3 of the intake manifold with the ends of the blades9. touching orv in close proximity to the walls of the up-draft-portion. Depending and diverging from said members Bare a plurality of vanes 10 reaching to the walls of the. up-draft portion 3. The vanes '10 f are spirally, twisted about one quarter turn or more and are formed from strips of metal 11. A

strip of metal 12' is bent to form vanes 10 having projecting feet 13 adapted to be clamped between gaskets"? and flanges 4 and 5 to hold the device in position. The diverging vanes 10 thus form a frame of the shape of a frustum of a cone or pyramid. V 7 Extending axially of this frustum are vane." 14 twisted lengthwise to give them a spiral form, the spirals beingin' opposed relationship so that each gives a different swirl to the mix-" ture engagedby'thems The vanes '14 and 15 are formed from a. strip of .riietal 16. Apertures '17, ,18, 19.; and '20 are "provided respectively in members 8, 11,12 and 16 for the reception of a rivet 21 that binds themembers together to form my device. Any suitable fas- .tening means can .be used instead of the rive-Z:

In the modification shown in Fig. 4 the members 108 have. projecting therefrom flattened portions 109v adapted to be clamped between flanges 104 and 105. This construction is fo use in engines infwhich'the Lip-draft portion 1030f. the manifold is'joiried to the manifold 102 as is shown .in Fig. 4, where there would be no place to position the feet 13 of the type of deviceshownin f I havefoundthatfthe eiiiciency'of the opera-- tion is increased if on vanes 14 -and-15Y I provide at least one dished portion 22iform'ed by striking up a portion of the metal. I have "here shown the vanes 14 and 15 formed with onii-g such dished portion butmore can be provided as desired. I have found that my device is especially suited for motors having up-draft to the manifold and best results are'there accomplished, althoughthe device works wel. in motors having downdraft or other types of manifolds. I i I In operation the mixture from the carburetor is shot in a jet 23, directly against the vanes 14 and 15 where it is swirled, forced outward. and, at the same time, thoroughly broken up and diffused. The vanes 10, also tend to swirl the mixture and" difi'use it when it impinges thereagainst as it comes from the carburetor or from vanes 14 and 15. 'When the mixture passes through the vanes 10, 14 and 15, it strikes the blades 9 and is further broken up, diffused, and swirled.

When in operation the blades and vanes act as eliminator plates and remove from the mixture sent therethrough any drops of entrained fuel that would ordinarily pass directly to the cylinders of the motor. When used in an updraft rnanifold the entrained fuel is intercepted and runs down vanes 10, 1 and 15. When my device is viewed in operation through a glass the fuel can be seen running down the vanes 10 where it is again caught up by the mixture flowing through the manifold and is further broken up and diffused.

'Ihe swirling motion given tothe fluid pass ing through my device tends to send the drops of a fuel by centrifugal force against the walls of the intake manifold where they condense out of the mixture and run down until they are caught in the blast of the incoming mixture and are again acted upon by the device until thoroughly broken up.

In use I have found my device to be especially effective because a thoroughly mixed homogeneous dry fuel and air mixture goes to the cylinders. Better power and a considerable saving in gasoline are thus effected, while the cylinder oil is able to fully lubricate'the pistons and the cylinders without dilution from the unburned fuel, and there is practically nocarbon deposited from unburned fuel Oil in the crank case of the engine does not become thinned and may be used indefinitely without changing.

I have described my invention in the embodiment preferred by me but wish to claim the same broadly as well as specifically, as pointed out in the appended claims.

Having thus described my invention; what I claim as new and desire to secure by Letters Patent is: a
